UNI-T lists the UT677A with internal resistance testing from 0.000mΩ to 3.100Ω, voltage testing from 0.000V to ±71.00V, temperature testing from -10.0℃ to 60.0℃, ≤200ms fast response, AC 1kHz four-terminal test method, 5000 data storage, USB interface, Bluetooth Android app support and measurement judgment function.\u003c\/p\u003e\n\u003ch2\u003ePro Tip\u003c\/h2\u003e\n\u003cp\u003eFor battery banks, do not judge weak cells by voltage alone; compare internal resistance trends across the full bank because a failing cell can still show acceptable voltage before load stress exposes it. Buy UNI-T UT677A from Kamadi Pakistan where discontinued stock or replacement guidance is required.\u003c\/p\u003e\n\u003ch2\u003eBuyer’s Selection Guide\u003c\/h2\u003e\n\u003cp\u003eChoose UT677A only if you specifically need this discontinued model or matching legacy equipment. For new purchases, consider the newer UT677A+\/UT677C family or bench battery testers depending on voltage, storage and reporting requirements.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBattery internal resistance testing\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eVoltage and temperature measurement\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAC 1kHz four-terminal test method\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e≤200ms fast response\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e5000 data storage with USB and Bluetooth app support\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eModel: UT677A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eProduct Type: Battery Internal Resistance Tester\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eInternal Resistance Range: 0.000mΩ to 3.100Ω\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eVoltage Range: 0.000V to ±71.00V\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTemperature Range: -10.0℃ to 60.0℃\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eResponse Time: ≤200ms\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMeasurement Method: 1kHz AC four-terminal method\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDisplay: 3.5-inch, 320×240 true-color screen\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eData Storage: Up to 5000 sets\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCommunication: USB and Bluetooth Android app\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eJudgment Function: PASS, WARNING and FAIL thresholds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBattery bank health checking\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRechargeable battery maintenance\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eBattery production inspection\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eUPS battery diagnosis\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eElectrolytic capacitor ESR checking\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Uni-T Instruments","offers":[{"title":"Default Title","offer_id":49513712386305,"sku":"211490355","price":78000.0,"currency_code":"PKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0731\/5659\/1873\/files\/kamadiplaceholder_39f6f5bc-6e6d-41e1-bf90-780206f87500.png?v=1739480679","url":"https:\/\/kamadi.pk\/products\/uni-t-ut677a-battery-internal-resistance-tester","provider":"Kamadi Pakistan","version":"1.0","type":"link"}
